Serial No. 133,309.

The invention relates in general to a machine for use in the brushing of car seats, backs, cushions and other similar articles hereinafter collectively referred to as car cushions and the present disclosure consti-- tutes a companion case with my copending application entitled Car cushion. cleaning machine, Serial No. 133,308 filed under even date now Patent Number 1,7 67 ,420, June 24, 1930. p 7

As is more particularly described in the above identified copending application, it is intended that the machine of which the present disclosure is a part be utilized to subject the car cushion,preferably while wet, to a vigorous brushing treatment and in the companion application there was disclosed a machine for successively presenting to the brush the several surfaces of the cushion to be treated.

More specifically defined the invention herein disclosed relates to that part of the complete machine which has to do with the brushing device which, comprises a rotating brush, mechanism for reciprocating the same back and forth across the car cushion or other surface to be brushed and control devices therefor. V

The primary object of the present invention is to provide a simplified form of brush and brush control which while featuring a structure by means of which the intensity of engagement between the brush and the sur-.

face under treatment may be under the sensitive manual control of the operator, as is more particularly outlined in the companion appli cation, there is provided at the same time a brush capable of having a powerful rotative movement at high speed and which can be actuated mechanically to have bodily reciprocatory movementback and forth across the surface under treatment and without attention on the part of the operator who is thus left free to attend to those functions of the machine which require personal supervision.

Another object of the invention is to provide a simple form of automatically actuated mechanism for causing a rotating brush to travel in one direction across the surface under treatment, to reverse its direction of travel when it reaches its limit of movement in both directions, torepeat its reciprocatory movement until interruptedby the operator and to provide-for. such reversal in travel positively, easily, without detrimental shock or strain on the reciprocating parts and in a waytending to minimize consumption of the mechanical energy driving the reciprocating and rotating brushv Another object of the invention isto provide an easily manipulated form of manual control for inaugurating andintercepting the bodily reciprocatory movement of the brush so that the engagement of the brush with the cushion may at all times be under the control of theoperator and convenient to. him as he is manipulating the cushion positioning means; while he is controlling the engagement of the brush with the cushion and otherwise occupied with the other'manually'manipulated parts of the complete machine. Still another object of the invention is t provide a simplified form of mechanism for insuringthe positive locking of the brush in an inoperative position spaced from the cushion Whenever it'is desired to intercept the bodily travel of the 'brushand incidentally the invention featuresthe disposition of the brush while rotating and not travellingout of brushing engagement with the cushion and at the same time to dispose the brush in an out of the-way position permitting the brush to maintain its high speed rotative motion during the; period while the A cushion is being shifted from one into another of its operative positions. 7

'Another object of the invention is to provide a form ofconstruction in which the several structural units are formed of the least number of separate parts and arranged convenient for ready replacement and repalr.

Various other objects and advantages of the invention will be in part obvious from an inspect-ion of the accompanying drawings and in part will be more fully set forth in the following particular description of one form of device embodying my invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

r Fig. 10 is a plan view looking down on the frontportion of the machine shown in Fig. 9 and showing the parts in the normal operative position of the brush travel.

In the following description and in the claims, parts will be identified by specific names for convenience of expression but they are intended to beas generic in their application to similar parts as the art will permit.

In the drawings and referring particulariv to Figs. 1 and 2 it is to be understood that the cylindrical brush 10 is mounted for rotary movement about its own axis and is designed to move with its axis vertically disposed back and forth along a vertical plane under the action of a source of power indicated symboli cally by the one-way main driving shaft 11. The shaft is shown to be a flexible device so as to provide sutiicient slack to move with the brush in its reciprocatory movement and is connected to be driven from an electric motor or other source of power (not shown).' The brush is mounted for itsperambulating movement in a brush carriage 12 which in turn is mounted for reciprocatory movement in a vertically extending skeleton support 13. This skeleton support is slidably mounted as a whole on the part of the machine 90 which carries the cushion C to be brushed and is identified in the copending application by the term brush carriage. cludes a pair of sliding bars 14 shown in cross section in 1 in plan in 10 and one of which is shown in side elevation in .Fig. 9 and'which provides the supporting engagement between the part herein illustrated and the main portion of the machine. The support 13 is moved bodily so as to bring the brush in varying engagement with the cushion to be brushed by means of a pair of carriage shifting arms 15 controlled by a single manually actuated control lever shown in a ig. 9. In this figure the lower fulcrum end of the rocking arm 15 is fixed in place so that the swinging of the lever will act to shift support 13 on rollers 91 carried by the machine part 90. Levers 15 have their upper ends pivoted to the support 13 and act to slide the brush support relative to the article tobe brushed, as is more fully described in my above identified patent. From the present disclosure it is to be understood that the support 13 has bodily movement as a whole relative to the cushion mounted on the main part of the machine in addition to the rotary and reciprocatory movement herein featured. The support 13 includes a pair of end frames16 connected by a plurality of parallel rods one of which 17 is journalled in the lower ends of the end frames and connects the arms 15. Another of these rods 18 is provided on its front side with a rack 19 and will be identified hereinafter as the lower rack rod. Still another of these rods 20 spaced above the rod 18 is similarly provided with a rack 21 and constitutes the upper rack rod, The uppermost rod 22 which is rotatably mounted in bearings 23 outlining the upper ends of the end frames will be referred to hereinafter as a control rod. The control rod is provided at its right end and adjacent the station of the operator with a control handle 24 by means of which the rod is rocked about its axis to stop and start the reciprocatory travel of the brush carriage.

The brush carriage is formed in effect of two separate parts, an upper hollow box-like structure 25 referred to hereinafter as the transmission casing, and a lower plate structure 26 referred to as a lower casing. The casings 25 and 26 are spaced apart vertically a distance sufiicientto accommodate the brush 10 therebetween and it is understood in gen eral that the structure is designed so as to contain the mechanism within a compact space and disposed so as to enclose movable parts in lubricant containing casings wher- The support iny ever possible and to leave exposed'the other structural parts. 1

The brush 10 constitutes part of a replaceable unit which includes a sleeve 2'? and at opposite ends of the brush are brush end plates 28 secured by screws 29 to the sleeve 27. The brush unit is demountably positioned on a vertically extending brush shaft 30 mounted in anti-friction bearings including a lower bearing 31 formed in the lower casing 26 and an upper bearing; 32 formed in the bottom 33 of the transmission casing 25 all as is particularly shown in Fig. 2. The lower end of the brush shaft is connected by means of av coupling 34 with the drive shaft 11. From this construction it is seen that the brush is connected directly to the main shaft and it is the intent to rotate this main shaft at high speed preferably by connecting the same to a high speed electric motor. The upper end of the brush shaft is intruded into the transmission casing 25 and is provided at its upper end with a worm-drive connection 35 turning a horizontally oisposed'intermediate drive shaft 36 rotatably mounted in bearings 37 formed on top of a bearing block 38 contained in the casing 25. To the opposite or right hand end of the shaft 36 is secured an intermediate bevelled gear 39 dieposed between and at all times in driving relation with a pair of, superposed endbevelled gears 40 and 41 coacting therewith to constitute a reversing drive motion particularly shown in Fig. 2. The end gears 40 and 41 are loose on a vertically disposed rack and pinion shaft 42 and are designed to be clutched thereto as shown in Fig. 2.

A double-cone three positioned clutch is disposed between the end gears and in position to drive the shaft 42 in both directions. The clutch includes end clutch elements 43 and 44 secured respectively to the end gears 40 and 41 and facing each other concentrically of the shaft 42. Positioned between the end clutch elements is an intermediate axially shiftable cone clutch element 45 designed when elevated with the rack shaft as hereinafter described to provide a driving connection from the shaft 36 to rotate the rack shaft clockwise and when depressed by the lowering of the rack shaft to rotate the same anti-clockwise. The third position of the intermediate element 45 as shown in Fig. 2 spaces the same from its driving relation with both of the end clutch elements and disposes the clutch in an inoperative, non-rotating position to intercept the driving connection between the main or brush shaft and the racl:

shaft.

The lower end of the shaft is journalled for rotary movement in a lower anti-friction bearing 46 contained in a lubricant casing 47 constituting part of the lower casing 26. The shaft 42 is also ournalled intermediate its length in an antifriction bearing 48 formed within the casing 25 andon topv of the bottom 33 thereof and exposed to. receive lower pinion 49 designed when in engagement 'ith the lower rack 19 to mesh .wlth the same as shown in Fig. 2 and assist'in advancing the carriage as a whole along the length-of the carriage support. shaft is provided just below the'transmission casing 25 with an upper pinion 50 designed to mesh with the upper rack 21 as previously described for the lower pinion and rack connection.

For the purpose of elevating or depressing the rack shaft and thus move the clutch element 45 to and from its three positions above referred to the shaft is mounted to'have a freedom of vertical or axial movement neces sary to effect the clutching and declutching engagement of thediiferential device therewith but as this movement is slight, in an actual embodiment of the invention being a Inatter'of about one-sixteenth of an'inch it is understood that the rack pinions while thus shifted axially are at all times in mesh with the relatively wide racks.

The rack shaft is moved from its position providing a driven engagement with the reverting dive motion. automatically as .the

carriage approaches the limit of movement in each reciprocatory direction across the surface of the cushion being brushed. For this purpose there is provided a snap acting shaft rocking, shifting and locking mechanism. Referring to the showing in Fig. 2 it is noted that a bed plate 51 extends transversely across the transmission casing and provides a bearing for the hub 52 of the upper differential drive gear 40. An antifriction bearing 53 is disposed between this clutch element and the bed plate. Demountably secured; to the upper face of the bed plate by means of screws 54 is a fixed nut 55. The nut is provided at its inner periphery with an annularsemi-spherical groove 56 in which groove are positioned spherical rollers 5. The rollers are contained partially in the annular groove 56 and partially W in a spiral groove 58 formed on a sleeve 59 loosely mounted on the reduced upper end of shaft 42 and held 1n place thereon by a nut 87.

Similarly the rack From this construction it is apparent that Y arotation or rocking movement of the sleeve 59 will cause the rollers to react on the spiral groove to shift the shaft 42 axially forthe limited distance necessary to effect a clutching and declutching of the clutch. To the extreme upper end of the sleeve 59 is clamped the split link 60 of a bell crank lever 61hereinafter referred to as a tripping or shaft rocking lever.

Rotatably mounted upon the fixed nut and projecting laterally therefrom is a snap acting locking plate 62 provided on one side with a plate tripping linger 63 adapted to be engaged by a stop on the control rod 22 hereinafter described. The locking plate 62 is limited in its swinging movement by stops 88 and 89 carried by the bed plate 51. The plate is provided with a longitudinally extending slot 6 1 in-which is slidably mounted a cam plate 65 and which plate includes a camming head 66 provided on its advance side with a double cam face formed of fiat bearing faces 6'? and 68 separated by a proj ecting point 69. A spring 7 0 positioned between the head 66 and a projection 71 on the plate 62 maintains the shaft 42 locked against accidental movement axially. The lever 61 which is mounted in advance of and opposite to the point 69 of the spring pressed camming head 66, is provided with two unequal length arms extending at right angles to each other. The shorter arm 72 is provided with a roller 73 engaged by either of the bearing faces 67 or 68 depending on the position of the lever 61 in relation to the plate 62 as shown in Figs. 3 and 5. The longor arm 7 1 hereafter referred to as a clutch tripping finger extends in the same general direction as the finger 63 normally at a slight angle to each other and both project towards and above the control rod 22 and extend out of the transmission casing.

The control rod 22 is provided adjacent opposite ends thereof with a pair of reversing stops 75 and 76. These reversing stops are disposed in the path of movement of the tripping finger 63 and the parts are so organizedthat the engagement of this finger with either of the reversing stops causes the lever 63 to swing the plate 62 as a whole and with it the camming head 66 to advance the point 69 past the roller 7 3 thus compressing the spring 70. As soon as the roller clears the point 69 the spring reacts to snap the lever 61 into its fully shifted position with :the roller engaging the face 67 or 68 on the side of the point 69 opposite to the side previously engaged by the roller.

From this construction it is seen that in the normal reciprocatory action of the de vice the fingers 63 and 74s are normally at an angle and are snapped past each other from the position shown in Fig. 3 into the position shown in Fig. In both positions the clutch element 45 is locked by the tension of the spring and is retained thereby until the tripping finger 63 is shifted in the oppoite direction by its engagement with the other reversing stop. This rotation of the rocking lever 61 causes the same to rotate the sleeve 59 over an arc sufficient to cause the spiral groove to turn relative to the rollcushion is avoided.

Normally the finger 76 passes over the stops 75 and 7 6 without engaging the same.

Should it be desired to stop the transverse bodily movement of the brush carriage the handle 24: is rotated into the position shown in Fig. 1 with the reversing stop 76 rotated slightly to bring it into the path of the finger 74. For this purpose the stop 76 at the left end of the machine is provided with an upstanding shoulder 77 which is disposed in the path of movement of the clutch tripping finger 74: as particularly noted in Figs. 1 and 6.

The stop 77 is so related to the clutch tripping finger ?4 that when the carriage next approaches the limit of its movement to the left of the machine as shown in'Fig. 1, the r cking lever 61 is shifted with the plate 62 and this of course shifts the point of the camming head so as to maintain the roller on the side onwhich it was when the moveient started. Difierently expressed, the locking plate 62 rotates with the rocking lever 61 and the snap action of the camming head is avoided. The effect of simultaneously moving both these members is to shift the clutch element 15 into the intermediate nonclutching position shown in Fig. 2.

In order to insure the positive locking of the carriage against accidental movement after the driving connection has been broken at the clutch, an automatically acting locking device is provided as shown in Fig. 1. This locking device includes alocking arm 7 8 pivotally mounted at one end to a bracket '29 forming part of the transmission casing 25 f and the free end of which arm is contained within a combined guideway and stop 80. A spring 81 acting 011 the free end tends normally to maintain thesame in the raised operative position shown in Fig. 1. The

control rod 22 is provided adjacent the left end thereof with a locking arm 82 which. when the control rod is rotated into position to stop the travel of the carriage is moved simultaneously into a depending position and into position to be engaged by the beveled end 83 defining the upper side of the locking arm 78. At the inner end of the bevel the locking arm is provided with a locking notch 8d into which the locking arm 82 is received and maintained in position by tension of the spring 81. The stop mechanism above de scribed is so disposed relative to all possible positions of the cushion that when the carriage is locked against its reciprocatory novement as shown in Fig. 2 the brush is ofiset to one side of and out of contact with the cushion and in this way any tendency of the rapidly revolving brush to burn the It is desired in someforms of machines of the type outlined to spray either the brush or the cushion under treatment, or both, with water or with a cleansing solution and for this purpose there is provided a perforated spray pine S5 supplied by means of a flexibie connection 85 with some suitable source of fluid supply. The spray-pipe is carried by and movable with the carriage and is disposed to direct the sprayed material as desired either onto the cushion C under treatment or on to the brush 10. p

In operation the machine is started usually by starting the motor driving the main shaft and this in turn sets the brush rotating and this rotary movement of the brush is maintained as long as the machine is in use. It is required in some brushing operations that the brush be rotated at high speed and as these brushes are of some material weight it is advisable to maintain the brush active during the short period of time while the operator is reversing tlie'position of the cushion to prevent successive parts to the brush ing operation as is more fully disclosed in the companion application. i p

The reciprocating action of thebrush is inaugurated by the operator lowering the control handle from the position shown in F i 1 into a partially depressed position. This has the effect of removing the locking arm 82 from engagement with the notched lever 7 8; Removing the stop 77 from the finger 74 perinits the tension of the spring reacting on the tripping finger to rerotate the rocking lever into position to bring the clutch into proper driving relation to causethe carriage to move from left to right of the machine in the direction indicated by the reverse showing in Fig. 1 and the carriage will be moved by the rack and gear connection illustrated until he carriage reaches the right of the machine and until the tripping finger 63 is moved into engagement with the adjacent side of the reversing stop 75. The rocking device is thus shifted from the full line position into the line indicated by dot and dash in Fig. 3. This will have the effect of rotating the spiral groove sleeve and shift the shaft 4:2 axially to effect a reversal in driving connection through the double acting clutch controlling the differential drive. The carriage will then start in its reverse travel from right to left of the machine and the engagement of the tripping finger 63 with the stop T6 at the left of the machine will act simultaneously to reverse the direction of drive and the carriage. will then move again in its left to right movement. This reversing of the carriage in its reciprocatory movementacross the machine will continue as long as the control rod is in its position to effect the reversal of the clutch.

lVith the control handle elevated as shown in Fig. 1 simultaneous action on both the tripping fingers will cause only a partial shifting of the clutch into the unclutched position previously described.

.By means of a device of the character described it is possible for the operator to set the brush in motion and then simply by the .ianipulation of a single control can set the machine into operation with the brush. reciprocating-back and forth across the surface being brushed and without necessity of attention on the part of the operator to control any part of the brush travel. Thisleaves the operator free to adjust the cushion and to control the intensity of engagementbetween the rotating and perambulating brush and the cushion surface with which it is in brushing engagement.
